It’s only a phase… Water you mean? Gneiss, tuff, & a little wacke The “do” point Geologists have their faults Jeopardy Test Review!
Approximately how many days does it take for lunar phases to repeat? It takes an average of 29 days, 12 hours, 44 minutes.
When did the first humans land on the moon? July 21, 1969
What is the phase of the moon in this picture? Waxing crescent
Draw the positions of the Earth-Moon- Sun when the moon is a waning gibbous.
What is the most commonly accepted hypothesis for the Moon’s formation? A Mars-sized body is believed to have hit the proto-Earth, blasting sufficient material into orbit around the proto- Earth to form the Moon through accretion.
What is the primary source of energy for evaporation? Solar radiation
Out of all the water on Earth, what percentage is potable? Three percent
What is a watershed? An area drained by a river and its tributaries.
What are three ways humans affect watersheds and the hydrologic cycle? Agriculture, timber harvest, mining, & urbanization.
Evaporation - molecules in a liquid state spontaneously become gaseous. Condensation - change of the physical state of matter from gaseous to liquid phase. Precipitation - condensation of atmospheric water vapor that is deposited on the earth's surface. Describe the processes that are involved in the water cycle.
Igneous, sedimentary and metamorphic What are the three main rock types?
Intrusive igneous rocks are formed within the earth; while extrusive igneous rocks are formed at the Earth’s surface. What is the difference between intrusive and extrusive rocks?
Non-foliated metamorphic rocks. BONUS: Define foliation. Amphibolte, marble and quartzite are examples of what type of rock?
Chemical sedimentary rocks form when minerals in solution become oversaturated and precipitate. Examples: halite & some limestones. How do chemical sedimentary rocks form? Give an example.
A common rock type found within continental crust is called __________. A common rock type found within oceanic crust is called ___________. granite. basalt.
Nitrogen – 78% Oxygen – 20.1% Argon – 0.9% List in decreasing order the three most abundant elemental gases in the atmosphere.
The Earth is closest to the sun in the winter. Seasons are the result of the Earth’s tilt. What season is the Earth closest to the sun? Describe the phenomenon that causes the seasons.
Wind chill is the apparent temperature felt on exposed skin, which is a function of the air temperature and wind speed. Therefore the car radiator will still read only -1°C. If the temperature outside is -1°C and the wind chill temperature is -25°C, what will your car’s radiator temperature be and why?
Pressure – barometer Wind speed – anemometer Temperature – thermometer Humidity – psychrometer What kinds of observational data are used in forecasting, how are they collected?
Increased cloud cover would reduce the solar radiation reaching the Earth's surface, thereby lowering the surface temperature. An increase in surface air temperature would have more water vapor present in the atmosphere. Therefore, increases in temperature will yield increases in atmospheric water vapor. The increased water vapor will act as a greenhouse gas, enhances the greenhouse effect and could lead to further warming. How can clouds affect surface temperatures?
Pangea (meaning 'all earth') was the supercontinent’s name. What is the name of supercontinent that existed about 250 million years ago?
(A) Lithosphere (B) Mid-ocean ridge or divergent margin (C) Trench or convergent margin (D) Asthenosphere (E) Mesosphere or mantle Identify…
1) Divergent boundaries occur where two plates slide apart from each other. 2) Convergent boundaries occur where two plates slide towards each other. 3) Transform boundaries occur where plates slide past each other. Describe the three different types of plate boundaries.
Convection, gravitational sliding, slab pull, ridge push. What are the four driving forces behind plate motion?
-Distributions of fossil plants and animals -Distributions of modern plants and animals -Geographic fit of the continents -Paleoclimatic oddities such as glacial till, coral reefs, and coal What types of evidence did Alfred Wegener use to support his theory of Continental Drift?
